There are a LOT of wires, and in all rainbow colors.
My son called his "his robot suit".
My son was NOT pleased about having to stay overnight. 6mo of in and out of the hospital (weeks on end inpatient, home for a few days, and right back again)... he'd reached his limit. He felt fine, he did NOT want to stay.
We have about an hours worth of cussing like a sailor in full stereo audio.
He did fine getting hooked up, playing some video games/tv time, but he was just "done" and not having it when it came time for lights out. But he didn't rip the wires off, and we did stay the night, and he was perfectly fine in the morning.
I forgot my pillow, though!
We had ours done through Childrens, so the whole place was set up just like a standard single (inpatient room). Bed for the kiddo, bed for a single parent, tv w/ gaming system (bring your own movies, or they had some to choose from), bathroom with shower, free wifi, reading lamp... all that jazz. Really, like a hotel room with med equipment.
If he hadn't been sick of hospitals, I think he would have had a really fun time.
